Implement DrawTexture functionality (#2747)

Browse source 
* Implement DrawTexture functionality

* Non-NVIDIA support

* Disable some features that should not affect draw texture (slow path)

* Remove space from shader source

* Match 2D engine names

* Fix resolution scale and add missing XML docs

* Disable transform feedback for draw texture fallback
